Nope - your justification does not mean it is not theft.
Anything you get from the artists should be paid for ...
You should go read Robert Fripp's blog - he talked about how he and King Crimson got cheated by their management company
and by large record companies for royalties. He realized there were a limited number of hours in a day so he could either practice and make music
or track down the money they were owned owned. So for nearly 10 years, he basically stopped playing concerts and doing records while he tried to
get acknowledgement from the company that they owned them all big time.
He is just recently reaching closure on this process ... and is now talking about reforming King Crimson.
Its pretty enlightening ... even the part about their music turning up on Spotify, even tho there was no contract for Spotify to play their music.
He'd file a copyright dispute, the music would be removed, then a bit later it would return.
Since Crimson hasn't toured in years - how would they get paid from "concerts and merchandises?"

Theft is theft, doesn't matter if its E.G. Management, Universal Music Group, or you downloading songs you never paid for.
